There is no way that anyone can say in what order the shots were taken? As I said before the person who did these murders must have been extremely disturbed so our so called "logic" may not apply? For instance if 10 shots were taken upstairs in the main bedroom wgo is to say whether they were all taken at the same time, thus emptying the gun. Or if a few shots were taken and the murderer went away to another part of the house and then went back again for another go? You simply cannot form an order of the sgots just by looking at the distribution of the shell cases or bullet wounds. Add to that the extra shell case found upstairs. I simply cannot just discount for the sake of my scenario remaining intact by stating that the shell case was taken upstairs accidentally on the shoe of one of the raid team?
The evidence that the shooting began int he bedroom is very solid so solid that no one here has been able to refute it and instead choose to just ignore it like you are doing now because that evidence harms the version you are trying to peddle of Sheila being responsible.
Taking into account the location of the shell casings, the bullets that exited/grazed the bodies, the number of shots the weapon holds, the locations on the body where victims were shot/the trajectories etc no Jeremy supporter has been able to come up with a way for the shooting to have happened where Sheila would have done the shooting and Nevill would have had the opportunity to make a call. Those who tried to do so made up wildly unrealistic claims that make no sense.
David's suggest Nevill was scared to face Sheila so ran away leaving his wife to be shot, June was shot 4 times then even though June was not dead and Sheila had more bullets left she just hung out waiting in the bedroom to see if Nevill would return thus permitting him to escape the house if desired. He was too scared to do anything so called Jeremy, then suddenly grew brave and left the phone off the hook for no reason and went up to confront Sheila unarmed though he could have armed himself.
He didn't grow brave till after he asked Jeremy to come then he grew a pair and went up and Sheila was hanging out waiting. Give me a break!
Adam is right that Jeremy supporters can't come up with a way for Sheila to have done it which matches the evidence (and the evidence includes Jeremy's own claims).
Jeremy supporters didn't come to the conclusion he is innocent by following the evidence they came to it by choosing to ignore the evidence or to discount evidence though they have no way of refuting the evidence so no rational basis to discount it or ignore it.
